The Whiteline Flat Out Positive Traction Kit for the Subaru will stiffen up the rear end for more precise handling. The Positive Traction Kit will reduce the movement of the rear sub frame during hard acceleration and cornering. The OEM mounts are made out of very soft material and have voids in them that cause flex. The Whiteline Positive Traction kit fills the voids in the OEM mounts to prevent wheel hop and get more power to the ground. This kit from Whiteline will increase rigidity without increasing noise or harshness. The Positive Traction kit installs easily with hand tools. All necessary hardware and instructions are included for your Subaru STI.
